Aside from the fact your understanding of what these other religions actually believe is in error, to me it doesn't matter how one describes wind. It's still wind. Are you arguing for correct descriptions? How is the description of something the same as the thing itself?
Partial truths often may be in contradiction with one another. But since when are partial truths absolute truth?
Not everyone in Christianity thinks like this, nor does everyone in Islam, nor in Buddhism, etc. It's simply a way that some humans think about truth. It's simply how some humans interpret truth, as absolute, black and white, I'm right and you're wrong, my perception or your perception, etc. This is either-or thinking, and it does not understand others' perceptions as valid. It deals with contradiction by eliminating the others, not be finding a reconciliation which means not holding your own perspective alone as absolute. It's the beginning of Wisdom to do this, which is humility to allow other perspectives of truth to hold validity as well as your own.
Christians don't believe in three gods. Neither do Hindus. They all believe in one God. But what I believe about the religions' ways of talking about God is that they are all partial truths, perspectives from a limited, finite understanding, and they all hold some truth to them.
Have you ever heard the parable of the blind men and the elephant?
It was six men of Indostan
To learning much inclined,
Who went to see the Elephant
(Though all of them were blind),
That each by observation
Might satisfy his mind.
The First approach'd the Elephant,
And happening to fall
Against his broad and sturdy side,
At once began to bawl:
"God bless me! but the Elephant
Is very like a wall!"
The Second, feeling of the tusk,
Cried, -"Ho! what have we here
So very round and smooth and sharp?
To me 'tis mighty clear
This wonder of an Elephant
Is very like a spear!"
The Third approached the animal,
And happening to take
The squirming trunk within his hands,
Thus boldly up and spake:
"I see," quoth he, "the Elephant
Is very like a snake!"
The Fourth reached out his eager hand,
And felt about the knee.
"What most this wondrous beast is like
Is mighty plain," quoth he,
"'Tis clear enough the Elephant
Is very like a tree!"
The Fifth, who chanced to touch the ear,
Said: "E'en the blindest man
Can tell what this resembles most;
Deny the fact who can,
This marvel of an Elephant
Is very like a fan!"
The Sixth no sooner had begun
About the beast to grope,
Then, seizing on the swinging tail
That fell within his scope,
"I see," quoth he, "the Elephant
Is very like a rope!"
And so these men of Indostan
Disputed loud and long,
Each in his own opinion
Exceeding stiff and strong,
Though each was partly in the right,
And all were in the wrong!
MORAL.
So oft in theologic wars,
The disputants, I ween,
Rail on in utter ignorance
Of what each other mean,
And prate about an Elephant
Not one of them has seen!
